easily applied to the .asement windows, strong and durable, neat in appearance,.con vcnient and eii'ective in use, and which is adapted to operate equally well at either the left side or the right side of the window.

Other objects and the advantages of the invention will be apparent to those skilled in the art from a carciul consideration of the following description of the preferred form of construction embodying the invention taken in connection with the accompanying drawings in which-- Figure 1 is a front elevational view of a casement window having the invention applied thereto; Fig. 2 is an enlarged sectional view taken on the line 2-2 of Fig. 1; Fig. 3 is a broken sectional view showing the window held in adjusted position at substantially 90 degrees from the closed position shown in Fig 2; Fig. 4: is a sectional view showing the window held in adjusted position at substantially 180 degrees from the closed position shown in Fig. 2; Fig. 5 is an enlarged broken cross sectional view taken on the line 5--5 of Fig. 4:; Fig. 6 isan enlarged cross sectional. view taken on the line Specification of Letters Patent.

6.( of Fig.4; Fig. 7 is an enlarged longitudinal sectional view taken on the line 7- of Fig. 4t, and 8 is an enlarged broken cross sectional view taken on the line 8-8 of Fig. 4.

As shown, the window is adapted to fit in the frame or casement l0, and it consists of the glass pane 11 mounted on the sash 12. The sash 12 is connected to the frame by hinges 18 which may be disposed at either the left side or the rigid side otthe window and which preferably project beyond the front of the frame and of the sash to afi'ord clearance between the frame and the sash for a roller curtain, not shown, when the Window is positioned at substantially 180 degrees from its closed position as in Fig. 4-.

To the rear of the hinges 13 011 the frame 10 is arranged a bracket 15 which has one end thereof secured, prei'ferably by screws 16, to the frame 10 and which has mounted thereon at the other end thereof a pivot pin 17 on which is mounted one end of a preferably expansible link 1.8. The link 18 preferably consists of the telescoping parts 19 and 20 which may be locked in adjusted position by means of a set screw 21, and it has its other end mounted on a pivot 22 which is mounted on one end of the arm 528 which latter has at its other end a knob 241; through which passes the stem 25 of a sliding block 26 which is arranged in a slideway 27 suitably arranged on the rear of the sash 12. The block 26 may be moved into or out of engagement with the flanges 28 of the slideway 27 by turning to the right or to the left the thumbscrew 29 on the stem 25.

From the foregoing it will be understood that the invention permits of the window being swung open and securely held in any desired position up to substantially 180 degrees from the closed position. hen it is desired to have the window completely open it can be swung to extend substantiallypan allel to its position when. closed and thus be safely out of the way in the room of a house.

While one form of construction embodying the invention has been particularly illustrated and described, many minor changes and modifications thereof will occurto those skilled in the art-wherefore the right is reserved to all such changes and modifications as do not depart fromthe spirit and scope of the invention as defined in. tbs appended claim.

I claim: bracket, and a clamping sliding connection The combination of a frame, a window, between said arm and said slideway. hinges at one side of the sash of the window In testimony whereof, I have signed my connecting the window to the frame, a slidename to this specification in the presence of 15 5 way on the rear of the sash, a bracket having two subscribing witnesses at Los Angeles, one end thereof secured to the frame and arcounty of Los Angeles, State of California, ranged to the rear of the hinges, a link adthis 27th day of January A.
